Specification of Letters Patent.

Patented. June 19, 1917.

Application filed October 23, 1916. Serial No. 128,15.

- invention being to provide simple means which is inexpensive in character and by which a push button or buttons can be connected with a switch operating lever in a rapid and easy manner.

In the drawings accompanying and formingpart of the present specification T have shown in detail one convenient form of embodiment of the invention which will be set forth fully in the following description. I

do not restrict myself to this exact disclosure; I may depart therefrom in several re spect-s within the scope of the invention defined by the claims following said descrip tion.

Referring to said drawings:

Figure 1 is a sectional view of a switch equipped with a connection involving the invention.

Fig. 2 is an elevation of a portion of the switch operating lever and button connected together.

Fig. 3 is a vertical sectional view of the parts shown in Fig. 2, the section extending centrally through the bearing opening in the lever and showing the push button in initial and final positions, the arrow indicating the motion between the two.

Like characters refer to like parts throughout the three views, Fig. 1 being on a smaller scale than the other two figures.

There are various types of two-button snap switches in use which involve a lever and buttons connected with the lever for operating the same in alternation. In ceris a little out of the ordinary. I provide a.

construction which can be made in a very inexpensive manner and can be connected with facility and rapidity to the coacting lever.

In Fig. 1 I have shown a switch operating lever 2 to which are connected the buttons 3 and s having shanks 5 and 6 connected with the outer ends of the said lever which is supported for oscillation between said ends in the box 7 of insulating material as common in the art.

As both buttons are the same in construction a detailed description of one will apply to the other, and in this connection reference will be had to Figs. 2 and 3 which illustrates in part the button3 and a por' tion of the lever 2. This button 3 has a shank 8 which I prefer to make from flat stock, as I can thus readily with the aid of suitable dies produce it from sheet material such for instance as brass. This flat shank may have the button 8 molded onto or otherwise associated with it. 't setswhen in operative position as shown by said Fig. 2 and in full lines in Fig. 3 edgewise or at right angles to the lever 2Q The said shank 8 terminates in a laterallyextending arm 9 furnished with a pendent extension 10, the shank 8, projection 9 and extension 10 bein in the same plane from which, as will be inferred, the shank with said projection and I extension can be easily made in the manner set forth. It should be noted that the projection 9 is at the extreme end of the shank which is the preferable construction and that it is also preferable that the pendent exten sion 10 should be located at the extreme end of the projection 9. The lever 2 has a bearing opening 11 to freely receive the projection 9, this projection constituting a fiat pivot for connecting the lever and shank lor relative swinging movement. The rojection 9, although oil less width than the diameter of the hearing or pivot opening 11 is not as wide as the shank and the extension 10 in turn is not as wide as the projection 9. This extension I might say acts as an effective stop to prevent accidental separation of the shank 8 from the lever 2 when the same are in working relation as shown in Fig. 2 and by fr-ll lines in Fig. 3.

As I have already observed the shank 8 with its button 3 can he quickly and easily connected with the lever For instance the following procedure may be adopted to will be inserted in the hearing opening When this is accomplished the ehani; A be tipped up to the vertiezfi poeitien a tl'ated by full lines in aid (MW 50 bring the shank i111, I;i1Tl'iC"" i() Z'Ihe year ee of the lever, and at the same Lime .in'ixvmhiee the projection 01: pivot portion 1') into the bearing opening 11 and mien hiring the i tension 10 in front of adjueem H) he forward side of the lever 3, so that when the buttons extend through their eustomzn pen forutions in the plate 12 on. the from ef the box 7 as indi mted by Fig. 1, said hn'tte cannot become accidentally sepni'ntmi free the switch operating lever What I claim. is:

The combination of a. switch ope lever having an. appmxznetely CiECUiH hem- 1 me: she iei'ei.
